CAR DOOR.

Application filed November 19, 1923. Serial No. 675,575.

To allv whom it may concern:

Be. it known that I, SOLOMON I-L URY, a citizen ofthe. United States, residing. at San Leandro, in the county. of Alameda and State of California, have'invented certain new'and. useful Improvements in Car Doors, of which the following is a specification.

This invention relates to freight car doors, andmore particularly. to' doors adapted to-operate longitudinally; of the car and which are mounted upon a movable frame and adapted to be manipulated vertically by manually operated'means, whereby said frame may be tilted upwardly and' outwardly to relieve any. strain from the inside against the doors, so that they'may be easily moved. from closed to open position.

Freight car doors of thepresent construction frequent-lyjump the track, or bind, and it is a commonpractice at such times to pry them open with a crowbar or like instrument; the object of this invention is to overcome this make-shift practice by the construction of a door which may be readily opened regardless of the position of the contents ofthe-car against the door The primary object of my invention is to construct a door for'freight cars which is non-binding and leak proof, and which may be readily openedat any time regardless of the condition of the load within the car.

Another object of the invention is'toconstruct a door frame and trackwhich is hung upon the side of tlie'car'and may beeasily removed or detached if desired.

Another object is. to construct a door which will drop tightly in place and wedge itself against the car door frame when in closed position, and thereby positivelyprevent any leakage of water between thedoor and frame of the can.

Other objects and advantages of the invention will appear in the suhjoined description of the accompanyingtwo sheets of drawings, in which:

Figure 1. is an elevation of a portion of a freight car showing my improved door as it appears in closed position.

Fig. 2 is a view analogous to Fig. 1, the door being shown in open position.

Fig. 3 is a vertical sectional detail showing the door in closed position and taken upon line 3-3 of Fig. 1.

Fig. 4 is a sectional detail showing the door and. supporting frame in raised position preliminary to opening the door.

Fig. 5 is a sectional detailillustrating the relation of the door and frame to the car body when in closed position, and taken upon the line of Fig. 1.

Fig. 6 is an enlarged end view of the winding drum for tilting the. door and frame with relation to the car body preliminary to opening the door.

Referring to the drawingsin detail, (10) designates the outer wall of an ordinary freight car having a door opening as indicated at (11). The door frame proper (12)v consists of upright pieces (13), (let) and top piece (15) secured to the outer wall (10) of the car and presenting a flush outer surface against which the door fits when in closed position.

The door supporting frame (16) is of rectangular shape and consists of upright bars (17), bottom guide angle bar (18) and top U-iron track bar (19). This frame is placed in position against the outer wall (10) of. the car and movably held by upper and lower sets of angle brackets (20) and (21.) The door (22) is hung in the supporting frame (16) and supported. by the guide rollers (23) attached to the upperface of said door by brackets ('24). The guide rollers (23) are grooved. and adapted tooperate upon the outer flange (25) of the U.-iron track (.19) of said supporting frame. The lower end of the door operates in. the bottomguide angle bar (18) and the outward movement thereof is limitcdby said bar.

Spacing, strips (26) and (27 are secured to the outer face of the car body and abut against the upright (14) of. the door-frame, and are flush with the outer face of said door frame and form wear plates for the door when moved to opened or closed po sition. The supporting frame (:16) is of rigid construction. and is braced at oneend by an angle brace (28) attached: to one of the upright bars (17) andthe U-iron track (19). The upper and lower sets of angle bracket (120) and (21;) are rigidly secured to the body of the car by bolts (29) and (30) and extend outwardly therefrom at rightangles then diverge upwardly. The brackets are set in such a position that when the door is in closed position, it is wedged tightly against the car door frame as shown in Figs. 3 and 5; and when the door is raised, as shown in Fig. 4, it moves away from the said car door frame.

The means for raising and lowering the supporting frame for the door, consist of a bearing bracket (31) Fig. 6, attached to and near the lower end of one of the upright bars (17), and a stationary supporting bracket (37) rigidly attached to the outer wall of the car body. The bracket (31) is provided with a winding drum journalled therein, and has a handle or crank (33) rigidly attached thereto. (32) is also provided with a ratchet wheel (34), and the bracket (31) is provided with a pivoted pawl (35) adapted for engagement with said ratchet wheel. A cable or like flexible connection (36) is secured at one end to the winding drum (32), and the other end is secured to the said supporting bracket (37).

Figs. 3 and 4 show the relative positions of the winding drum and stationary bracket (37). The cable is attached to the outer end of the supporting bracket and extends downwardly and inwardly to said winding drum, so that upon operation of the crank handle to tilt the supporting frame, the tendency is to pull upwardly and outwardly on said frame as it is raised to the position shown in dot and dash lines in Fig. 1, and solid lines in Fig. 4.

A U-bracket (38) is rigidly attached to the upper face of the U-iron track (19), and extends in position to engage a pin extending outwardly from the bracket (40), which is attached to the upper portion of the car body. Said bracket is attached directly above the upright (17) and the entire supporting frame oscillates upon the pin (39) of the bracket (40) and is thereby held from longitudinal movement.

It will be noted with reference to Fig. 4 that the supporting frame has been drawn up and away from the door frame, by operation of the winding drum, until the flexible connection or cable is in a nearly vertical position, as shown, and when in this position the door (22) may be easily moved to open position. The tilting of the supporting frame and U-iron track (19) tends to urge the door to open position, and when in this position it may be moved with a minimum effort on the part of the operator. A guide bracket (41) with a hook-shaped upper end is attached to the outer face of the door (22), and hooks over the outer flange of the track (19) to maintain the rollers (23) in position upon the tracks, and

The drum.

to prevent the door from falling outwardly in case the rollers jump the track.

Upright grooves (42) are formed in the outer faces of the uprights and (14) of the car door frame and a groove (43) is formed in the outer face of the top piece (15), said groove (43) extending downwardly from the center of the top piece (15) and communicating with the grooves (42). The door (22) when in closed position is wedged tightly in place against the car door frame, and in order to prevent any possible leakage of water between the door and car door frame, the drain grooves are provided, and in case any water should enter between said door and frame it would be carried away by the drain grooves and prevent any possible damage to the contents of the car.

Having thus illustrated and described my invention in its preferred form I wish it understood that the same may be modified practice suggests. Therefore, the patentprotection that I desire, is all of that which comes within the spirit and scope of the invention as claimed.

Claims.

1. A freight car door comprising, a supporting frame and track, a door slidably mounted upon said track and means for tilting said supporting frame and door vertically and laterally simultaneously with relation to the car body.

2. A car door comprising, a supporting frame and door track, a. door slidably mounted upon said track and means for oscillating said track vertically and laterally simultaneously with relation to the car body upon a given pivot point.

3. In a car door, a pivoted supporting frame therefor adapted to be oscillated vertically and laterally simultaneously with re lation to the car body and door opening, a longitudinally movable door mounted in said supporting frame and means connected with the car body and supporting frame to oscillate said supporting frame and movable door.

4. In a freight car body, the combination of a door supporting frame adapted to oscillate about a given point upon said car body, a movable door mounted in said frame, wedging means mounted upon said car body adapted to be engaged by said supporting frame at its four corners, and manually operated means connected to said car body and one end of said frame for tilting said supporting frame to release-the door and said frame from said wedging means.

In testimony whereof I a'tfix my signature.
